Calibrating Analog Meters with the 5080A Multi-Product Calibrator (1.55 MB)

Calibrating portable analog meters or analog panel meters can be challenging. These types of meters have low impedance that requires a high drive capability from the calibrator. A typical electrical calibrator might trip and display an error message: “Compliance exceeded.” Similar problems can occur when calibrating digital workload with low impedance.

Calibration professionals often use a power supply and a bench digital multimeter to provide the high compliance and accuracy required for analog meter calibration. However, there are drawbacks to this solution. This application note points out those drawbacks and explains how the Fluke 5080A Multi-Product Calibrator is a better solution for calibrating analog meters.
